The probability that the fourth marble amy picks is black is. If amy picks a black marble in the fourth attempt, the probability that in the fifth attempt she will pick a red or a black marble is.

Answers

Answer 1

The probability that the fourth marble Amy picks is black: This probability cannot be determined without knowing the total number of marbles and the number of black marbles.

The probability that, if Amy picks a black marble in the fourth attempt, she will pick a red or a black marble in the fifth attempt: This probability cannot be determined without knowing the total number of marbles and the number of red and black marbles.

Probability is a measure of the likelihood of an event occurring. To calculate the probability of an event, you need to know the total number of outcomes and the number of outcomes that are favorable to the event. For example, if there are 10 marbles in total and 4 of them are black, the probability that Amy will pick a black marble on the fourth attempt is:

Probability = Number of black marbles / Total number of marbles = 4/10 = 0.4

Similarly, if Amy picks a black marble in the fourth attempt and there are a total of 10 marbles, with 4 of them being black and 6 of them being red, the probability that she will pick a red or a black marble in the fifth attempt is:

Probability = (Number of red marbles + Number of black marbles) / Total number of marbles = (6 + 4) / 10 = 0.8

x = 50, y = 61

Step-by-step explanation:

y + 8 + 2x + 11 = 180°

y + 2x = 161°

the total of the interior angles of the 5 sided polygon is:

(180 x 5) - 360 = 540°

540 = 98 + 98 + 125 + 108 + 2x + 11

2x = 100

x = 50°

y + 2(50) = 161

y = 61°

Please help me on this assignment Its importantDiana NyadMarathon Swimmer(1) On August 19, 1979, Diana Nyad began her historic swim from Bimini, Bahams, to Jupiter, Florida, 89 miles away. (2) Nyad, a veteran of several marathons swims, wants to set a new world record for the longest open-water swim. (3) In 1974 she swam across Lake Ontario from north to southa difficult crossing because of the swift current of the Niagara river. (4) A year later she completed a swim of more than 25 miles around New York Citys Manhattan Island, she had battled dangerous currents for nearly eight hours. (5) The swim from the Bahamas to Florida, however, would be far more treacherous than anything she had previously attempted. (6) It would require exceptional physical and mental strength.(7) Nyad, like other long-distance swimmers, knew that every marathon swim is a grueling physical experence. (8) In earlier marathons she had become delirious from the fatigue of continuous stroking, kicking, and breathing. (9) She also knew that her senses would become impaired. (10) Her dark goggles would fog over, making it impossible for her to see. (11) Even though her coach and crew were in a support boat only twenty feet away, the tight rubber swim cap that covered her ears would prevent her from hearing thecoachs whistle. (12) The salt water would even affect her senses of taste, touch, and smell.(13) In addition to extreme physical exhaustion, Nyad was aware of the many dangers she would face in the water. (14) During earlier marathons schools of jellyfish had repeatedly stung her. (15) On Nyads Bahamas-to-Florida swim, a shark appeared.(16) Nyads crew was prepared with an electronic shark shield. (17) Crew members sent out a wave of electricity that did not harm Nyad but affected the shark and cause them to turn away. (18) Electricity can be used to repel many other kinds of animals. (19) Despite all the obstacles she faced, Nyad successfully reached her goal. (20) She was exhausted but happy. (21) She waded onto the Florida shore.
