Answer:

The correct answer is:

(A) 0.55

Step-by-step explanation:

This probability distribution means that we have these following probabilities:

[tex]P(X = 0) = 0.05[/tex]

[tex]P(X = 1) = 0.15[/tex]

[tex]P(X = 2) = 0.35[/tex]

[tex]P(X = 3) = 0.30[/tex]

[tex]P(X = 4) = 0.15[/tex]

What is the probability that in a given game the Lions do not score more than 2 goals?

This is the following probability.

[tex]P = P(X = 0) + P(X = 1) + P(X = 2)[/tex]

[tex]P = 0.05 + 0.15 + 0.35[/tex]

[tex]P = 0.55[/tex]

The correct answer is:

(A) 0.55
