Question

The probability of Kaia scoring an A on her

math test (event A) is 0.82, and the probability of
Kaia scoring an A on her history test (event B) is
0.85. The probability of her scoring an A on both
tests is 0.697. Given this information, are events
A and B dependent or independent?

Answer 1

dependent

Explanation:

the probability of 0.697 is dependent upon Kaia scoring an 82, followed by an 85 on the other test

Check: multiply 0.82 by 0.85 and your will get 0.697
