Chapter 13.3, Problem 3CYU

To determine

To calculate; to find the probability that either Greg’s partner or the pile have the joker

Answer to Problem 3CYU

Solution: $P\left(Greg\text{'}spartnerorpilehasjo\ker \right)=\frac{13}{33}or39.3\%$

Explanation of Solution

Number of cards in the pile $=43-4\left(10\right)=3$

Number of favorable outcomes $=$ Number of cards that Greg’s partner and pile have $=10+3=13$

Total number of possible outcomes $=3\left(10\right)+3=33\left(excludingGreg\text{'}scards\right)$

  $\begin{array}{l}P\left(Greg\text{'}spartnerorpilehasjo\ker \right)=\frac{numberoffavorableoutcomes}{numberofpossibleoutcomes}\\ =\frac{13}{33}\end{array}$
