The formula for probability is:
Probability = number of successful events / number of total events
In this case, the number of total events is equivalent to the total number of peas.
number of total events = 402 + 38
number of total events = 440 peas
Since we want to estimate the probability of getting a green pea, therefore
number of successful events = 402 green peas
Using the formula, the probability for getting a green pea is:
Probability = 402 / 440
Probability = 0.91 (ANSWER)
The result is not reasonably close to the value of ¾ or 0.75.
