The value of the probability P(A and D) is 0.30
How to determine the probability P(A and D)?
Using the probabilities on the tree diagram, we have the following parameters
P(A) = 0.5
P(D/A) = 0.6
The probability P(A and D) is then calculated using the following formula
P(A and D) = P(A) * P(D/A)
Substitute the known values in the above equation
P(A and D) = 0.5 * 0.6
Evaluate the product
P(A and D) = 0.30
Hence, the value of the probability P(A and D) is 0.30
