Question

The probability that Yuri will make a free throw is 0.3. The probability that he will make two consecutive free throws is _______. The probability that he will make the first and not the second in two free throws is _______. The probability that he will make neither of the two free throws is _______.

Answer 1

1. 0.09

2. 0.21

3. 0.49

Explanation:

If the probability that Yuri will make a free throw is 0.3, then the probability that Yuri will not make a free throw is 1-0.3=0.7.

1. The probability that Yuri will make two consecutive free throws is

`0.3\cdot 0.3=0.09`

2. The probability that he will make the first and not the second in two free throws is

`0.3\cdot 0.7=0.21`

3. The probability that he will make neither of the two free throws is

`0.7\cdot 0.7=0.49`
