75% of all people enjoy sports. everyone else doesn't. let the
random varible x be the number who doesn't enjoy sportamong 7
randomly selected persons.
- find the probability that no more than 6 of the 7do not
enjoy sports?

The probability that no more than 6 of the 7 do not enjoy sports = 0.9999.

Step-by-step explanation:

Given : The proportion of people enjoy sports : p= 0.75

So , the proportion of people doesn't  enjoy sports = 1-0.75=0.25

Let the  random variable X be the number who doesn't enjoy .

Total number of people randomly selected : n= 7

Using Binomial distribution , the probability of getting x success :

, n= Number of trails , p= Probability of getting success in each trial.

The probability that no more than 6 of the 7 do not  enjoy sports :

Hence, the probability that no more than 6 of the 7 do not enjoy sports = 0.9999 .
