Question

The probability of Samantha scoring an A on a geology test (event A) is 0.46, and the probability of Judith scoring an A on the same test (event B) is 0.54. The probability of both Samantha and Judith scoring an A is 0.2484. Given this information, which statement is true?

Answer 1

which statement?

Answer 2

since \(.54\times .46=.2484\) the events are independent, so i guess they are not cheating off each other
do you have statements to check?

Answer 3

Don't know your statements but the probability that at least one of them gets an A is
$$
\large{
P(A~OR~B)= P(A)+P(B)-P(A~AND~B)\\
=0.46+0.54-0.2484=0.7516
}
$$
