Answer:
Step-by-step explanation:
To find the probability of a certain set, we must add the probability of the points that are contained in the specific set.
a) P(A): Add the probability of 1,3,5. That is P(1)+P(3)+P(5) = 0.5
b) . This set has no points in it, so its probability is 0.
c) P(A\cup B \cup C): Add the probability of 1,2,3,4,5,6. So, it is 1.
d) . P(C) is the probability by summing 5,6,2 so P(C) = 0.5. So
e) That is, all the points that are in A but not in C. So add 1,3. Then the probability is 0.4
e'), using the definition of conditional probabily and results a,b.
f) Two events are mutually exlusive if the probability of their intersection is 0. In this case A and C are not mutually exclusive, since is the probability of 5, that is 0.1. Since 0.1>0, they are not mutually exclusive.
Answer:
1.60% probability that a randomly selected passenger car crash DOES result in a rollover
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
83,600 U.S. passenger cars rolled over when they crashed, so
Total outcomes:
83,600 U.S. passenger cars rolled over when they crashed and 5,127,400 passenger cars did not roll over when they crashed. So
What is the probability that a randomly selected passenger car crash DOES result in a rollover
1.60% probability that a randomly selected passenger car crash DOES result in a rollover
