Bradley wanted a blue gumball and a green gumball from a vending machine. There were 15 blue gumballs, 12 yellow gumballs, 2 green gumballs, and 16 purple gumballs. How many times would you expect to get a blue gumball or green gumball if a gumball was taken out 250 times?

Respuesta :

Answer: 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

[tex]\frac{15}{45}+\frac{2}{45}=\frac{17}{45}[/tex]

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

[tex]\frac{17}{45}\times 250=94.4[/tex]

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.
