P(train arriving) = 0.8
P(train arriving on time) = 0.84
P(train arriving late) = 0.86
0.8 x 0.86 = 0.688
Answer: 0.688
Hope it helped :)

Answer:
The ratio is 15:5 or 3:1. If Marianne is 3 years old, her brother is 1. And it is proportional...

Answer:
Step-by-step explanation:
Let us assume that if possible in the group of 101, each had a different number of friends. Then the no of friends 101 persons have 0,1,2,....100 only since number of friends are integers and non negative.
Say P has 100 friends then P has all other persons as friends. In this case, there cannot be any one who has 0 friend. So a contradiction. Hence proved
Part ii: EVen if instead of 101, say n people are there same proof follows as
if different number of friends then they would be 0,1,2...n-1
If one person has n-1 friends then there cannot be any one who does not have any friend.
Thus same proof follows.
The smallest value of k when the LCM(Lowest common factor) of 14 and
k is 140 is 10.
<h3>What are factors?</h3>
Factors are numbers or algebraic expressions that divide another number or expression evenly
From the question,
If 14 and k is 140
⇒ (14×k) = 140
⇒ 14k = 140
⇒ k = 140/14
⇒ k = 10
Hence, the smallest value of k is 10.
