Bradley would expect 94 times to get a blue or green gumball.

Step-by-step explanation:

Since we have given that

Number of blue gumballs = 15

Number of yellow gumballs = 12

Number of green gumballs = 2

Number of purple gumballs = 16

Total number of all gumballs = 45

Probability of getting either a blue gumball or green gumball be

So, Expectation of getting a blue gumball or green gumball if a gumball was taken out 250 times :

Since we know that it must be less than 94.4.

So, the nearest smallest integer will be 94 times .

Hence, Bradley would expect 94 times to get a blue or green gumball.
