Question

One hundred football players were asked how many broken bones they have suffered. The probability distribution shows the probability of the number of bones broken by a football player.

What is the probability that a football player has suffered more than 3 broken bones?

Enter your answer, as a decimal, in the box.

Answer 1

The probability for a football player to suffer more than three roken bones will be the the sum of probabilities for 4 broken bones and five broken bones. Looking at the chart provided we can see that the probablity for 4 four broken bones is P(4)=0.10, and for 5 broken bones is P(5)=0.15. Thus the probaility,
P(x>3)=0.10+0.15=0.25.
