Question

if kebe is late for school, the probability is that lilian is late for school is 0.7. If kebe is not late for school, there is still a probability of 2.0 that lilian will be late a) copy and complete the tree diagram. b) What is the probability that lilian will not be late, given kebe is late

Answer 1

Answer:

Correct option is C)

Since, the probability that Vikram is late for school in the morning is 0.1, he will be on time 0.9 of the times.

So, number of times Vikram can be expected to be on time in 20 mornings =0.9×20=18

Step-by-step explanation:

hope this helps uh ✌;-)

Answer 2

Answer:

b) 0.3

Step-by-step explanation:

Given that Kebe is late for school. that means its a conditional probability. so when Kebe is late P(Lilian is late) = 0.7

so P(lilian not late) = 0.3
