Chapter 0.3, Problem 18E

To determine

To find Probability of outcome where cards are drawn randomly from a hat numbered 1 to 28.

Answer to Problem 18E

  $P=\frac{27}{28}$

Explanation of Solution

Given Information: Cards are drawn randomly from a hat numbered 1 to 28

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

Calculation:

When cards are drawn randomly from a hat numbered 1 to 28 numberof outcomes is 1.

To find the probability of outcome where cards are drawn randomly from a hat numbered 1 to 28 is not 1, the possible outcomes will be 27.

  $P\left(not1\right)=\frac{PossibleOutcomes}{TotalOutcomes}$

So-

  $P=\frac{27}{28}$

Hence the final answer is,

  $P=\frac{27}{28}$
