discussion 4

In Exercises 39 – 44, refer to the following information. When playing bingo, 75 balls are placed in a bin and balls are selected at random. Each ball is marked with a letter and number as indicated in the following chart.

$$\frac{\text{B}}{1-15}\frac{\text{I}}{16-30}\frac{\text{N}}{31-45}\frac{\text{G}}{46-60}\frac{\text{O}}{61-75}$$

For example, there are balls marked B1, B2, up to B15; I16, I17, up to I30; and so on (see photo). Assuming one bingo ball is selected at random, determine

1. the probability that it does not contain the letter B.

Question number 2

Roll a Die In Exercises 19 –22, a single die is rolled one time. Determine the probability of rolling

1. a number greater than 3 or less than 5.
