Chapter 0.3, Problem 9E

To determine

To find Probability of outcome where a coin is randomly selected.

Answer to Problem 9E

  $P=\frac{11}{14}$

Explanation of Solution

Given Information: A coin is randomly selected

Formula Used : $P=\frac{PossibleOutcomes}{TotalOutcomes}$

Calculation:

Total outcomes-

  $65+27+30+18=140$

When a coin is randomly selected total number of outcomes is 1.

Not dime-

  $65+27+18=110$

To find the probability of outcome where a coin is randomly selected is not a dime,the possible outcomes will be 110.

  $P\left(not\dim e\right)=\frac{PossibleOutcomes}{TotalOutcomes}$

So-

  $P=\frac{110}{140}$

Hence the final answer is,

  $P=\frac{11}{14}$
