The probability that the red die shows an even number or the green die shows an even number is 3/4
How to determine the probability?
The sample space of a die is:
S = {1,2,3,4,5,6}
There are 3 even numbers in the above sample space
This means that the probability that a die shows an even face is:
P(Even) = 3/6 = 1/2
So, we have:
P(Even Red) = 1/2
P(Even Green) = 1/2
The required probability is then calculated as:
P = P(Even Red) + P(Odd Red) - (P(Even Red) * P(Odd Red))
This gives
P = 1/2 + 1/2 - 1/2 * 1/2
Evaluate
P = 3/4
Hence, the probability is 3/4
