Chapter 0, Problem 16PFG

To determine

To calculate the probability

Answer to Problem 16PFG

  $P(redOrBlues)=0.526$

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 red or blue chips,

  $3+7$

On solving,

  $10$

Substituting the values,

  $P(redOrBlue)=\frac{10}{19}$

On solving,

  $P(redOrBlue)=0.526$
