2 answers:
<h2>Answer:</h2>
The formula that is used to calculate the probability of independent events A and B are:
D. P(A and B)=P(A)·P(B)
<h2>Step-by-step explanation:</h2>Independent events--
Two events A and B are said to be independent if the happening of one event do not affect the happening of the other event.
For example-- The probability of getting two heads on rolling a die two times.
Hence, the formula that calculate the probability of independent events A and B is given by:
