The P(X < 3) from the probability distribution graph is 0.3
What is P(X < 3)?
Probability simply means the likelihood of an event happening. It is the ratio of the number of favorable outcomes to the total number of outcomes.
From the probability distribution shown;
P(X < 3) = (1/2) × 3 × (0.20)
P(X < 3) = 1.5 ×0.20
P(X < 3) = 0.3
Therefore, P(X < 3) equals 0.3
