Answer 2

Answer:

The probability of 84 is 0.1.

Step-by-step explanation:

According to probability theory, in any event, the sum of the probability of all possible outcomes is always one.

Therefore,

P(X) = 1

P(20) + P(39) + P(84) + P(86) = 1

0.1 + 0.5 + P(84) + 0.3 = 1

P(84) = 1 - 0.9

P(84) = 0.1

Therefore, the probability of P(84) is 0.1.
