In this question, the probability that Sheila walks is 0.65 and if she walks, which mean the probability to take cycle is 0.35. The probability that shell be late if walking is 0.4 and if she cycles the probability that shell be late is 0.1
The probability that she will be late:
0.65*0.4 + 0.35*0.1= 0.26+ 0.035= 0.295
The probability that she will not be late:
1-0.295= 0.705= 70.5%
The probability that she will be late:
0.65*0.4 + 0.35*0.1= 0.26+ 0.035= 0.295
The probability that she will not be late:
1-0.295= 0.705= 70.5%
The probability that on any one day, sheila will not be late for school would be 0.705.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
It is given that
Probability she walks and is not late = 0.65 x 0.60
= 0.39.
Probability she cycles and is not late = 0.35 x 0.9
= 0.315
Therefore P(not late) = 0.39 + 0.315
= 0.705
Thus, the probability that on any one day, sheila will not be late for school is 0.705.
