If Max makes 45 out of 60 shots with the basketball, how many would you expect him to make if he only shot the basketball 15 tim

exis [7]

Answer:

Step-by-step explanation:

Probability of Max making a shot is 45/60=¾

Here, probability, p=¾ or 0.75

The trials n=15

E=np where E is expectation

Now, when the shots out of 15 trials will be given by np=15*¾=11.25 shots

Rounded off to the nearest interger, this is approximately 11 shots.

Therefore, the possible number of shots in 15 trials for Max is equivalent to 11

brilliants [131]

Answer:

0.18% probability that they are all women

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the senators are chosen is not important, so the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Desired outcomes:

3 women, from a set of 13. So

$D = C_{13,3} = \frac{13!}{3!(13 - 3)!} = 286$

Total outcomes:

3 senators, from a set of 100. So

$T = C_{100,3} = \frac{100!}{3!(100 - 3)!} = 161700$

Probability;

$p = \frac{D}{T} = \frac{286}{161700} = 0.0018$

0.18% probability that they are all women
