The probability of walking to school is 7/15
How to determine the probability of walking to school?
The tree diagram represents the given parameter
The following parameters are represented on the tree diagram
- P(Rain) = 2/5
- P(Rain and walk) = 1/6
- P(No rain) = 3/5
- P(No rain and walk) = 2/3
The probability that a student walks to school is then calculated as
P = P(Rain) x P(Rain and walk) + P(No rain) x P(No rain and walk)
Substitute the known values in the above equation
So, we have
P = 2/5 x1/6 + 3/5 x 2/3
Evaluate the products
P = 1/15 + 6/15
Evaluate the sum
P = 7/15
Hence, the probability is 7/15
