1 answer:
Answer:
Speed of car B is 33 km/h and speed of car A is
Step-by-step explanation:
Let speed of car B be km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A = km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours = km =
km
Distance travelled by car B in 4 hours = km
Also, cars A and B are 312km apart after 4 hours.
Speed of car B is 33 km/h and speed of car A is

Answer:
a) 1/6
b) 1/36
c) 1/720
d) 1/3
Step-by-step explanation:
a) Any of the six comics can perform in the fourth place, so there is one chance in six that Comic F is the one that performs fourth.
b) In this case, we have two conditions. Both are independent of each other, so the probability of both happening is the product of the probabilities of each happening individually:
c) This combination is one in all possible orders of perform. The amount of combinations of orders is n!=6!=720 possible combinations. So the probability of this specific order is:
d) In this case, of the six possible comics performing in the last place, we calculate the probability of 2 of them being in that place. So the probability is:
