Answer:
2/3
Step-by-step explanation:
Event A = 1/6
Event B = 3/6 = 1/2
P(A or B) = P(A) + P(B)
= 1/6 + 1/2
= 4/6
In simplest form = 2/3
The probability of event A or event B is 2/3.
Probability is "the possibility that deals with the occurrence of the random of event".
According to the question,
Number of sides of die n(s) = 6
Event A is rolling a die of side 6 and event B is rolling a die of prime number sides
Formula for probability = [tex]\frac{Number of favorable event}{Totalnumber of events}[/tex] .
Probability of event A = 1/6
Probability of event B = 3/6 =1/2
Probability (event A or event B) = 1/6 + 1/2
=2/12+6/12
=8/12 = 2/3.
Hence, the probability of event A or event B is 2/3.
