Final answer:
To find the missing probability, use the formula P(B) = P(AUB) - P(A) + P(ANB), substitute the given values, and calculate the result. The final probability is approximately 0.8.
Step-by-step explanation:
The missing probability can be found using the formula:
P(B) = P(AUB) - P(A) + P(ANB)
Substituting the given values, we have:
P(B) = 101 - 0.2 + 4 = 101.8
Therefore, the probability P(B) is approximately 0.8.
