Chapter 0.3, Problem 12E

To determine

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

Answer to Problem 12E

  $P=\frac{113}{140}$

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 nickel-

  $65+30+18=113$

To find the probability of outcome where a coin is randomly selected is not nickel, the possible outcomes will be 113.

  $P\left(notNikel\right)=\frac{PossibleOutcomes}{TotalOutcomes}$

So-

  $P=\frac{113}{140}$

Hence the final answer is,

  $P=\frac{113}{140}$
