Chapter 0, Problem 17PFG

To determine

To calculate the probability

Answer to Problem 17PFG

  $P(Not\mathrm{Re}d)=0.632$

Explanation of Solution

Given information:

Number of blue chips 3

Number of red chips 7

Number of yellow chips 4

Number of green chips 5

Formula used:

  $P(a)=\frac{NumberOfFavorableOutcomes}{TotalOutcomes}$

Calculation:

Total number of chips,

  $3+7+4+5$

On solving,

  $19$

Total number of not red chips,

  $3+4+5$

On solving,

  $12$

Substituting the values,

  $P(Not\mathrm{Re}d)=\frac{12}{19}$

On solving,

  $P(Not\mathrm{Re}d)=0.632$
