In a survey of adults who follow more than one sport, 30% listed football as their favorite sport. you survey 15 adults who follow more than one sport. what is the probability rounded to the nearest tenth that fewer than 4 of them will say that football is their favorite sport?

0.5

Step-by-step explanation:

Binomial probability formula :-

, where P(x) is the probability of getting success in x trials , n is the total trials and p is the probability of getting success in each trial.

Given : The probability that the adults follow more than one game = 0.30

Then , q= 1-p = 1-0.30=0.70

The number of adults surveyed : n= 15

Let X be represents the adults who follow more than one sport.

Then , the probability that fewer than 4 of them will say that football is their favorite sport,

Hence, the probability rounded to the nearest tenth that fewer than 4 of them will say that football is their favorite sport =0.5

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

chase is right because he already been to the swings and he know how far it will be to get there
