100 random students are surveyed outside of the student center on campus. Let V denote that the student has a Visa credit card and let M denote that the student has a Mastercard credit card. 40 people had a Visa card, 32 had a Mastercard, and 12 had both a Visa and Mastercard. Calculate the following. hade Visa care, 3a hace a mastercard, and 12 had both (a) P(M|V) =.(b) P(MCV) =. (c) P(VIM) =. (d) P(VC I M) =.

Ответ:
(a) The value of P (M | V) is 0.30.
(b) The value of
is 0.70.
(c) The value of P (V | M) is 0.375.
(d) The value of
is 0.625.
Step-by-step explanation:
It is provided that,
V = a student has a Visa card
M = a student has a Master card
N = 100, n (V) = 40, n (M) = 32 and n (V ∩ M) = 12.
The probability of a student having visa card is:
The probability of a student having master card is:
The probability of a student having visa card and a master card is:
The conditional probability of an event, say A, given that another event, say B, has already occurred is,
(a)
Compute the probability that a student has a master card given that he/she has a visa card also, i.e. P (M | V) as follows:
Thus, the value of P (M | V) is 0.30.
(b)
Compute the probability that a student does not have a master card given that he/she has a visa card also, i.e.
as follows:
Thus, the value of
is 0.70.
(c)
Compute the probability that a student has a visa card given that he/she has a master card also, i.e. P (V | M) as follows:
Thus, the value of P (V | M) is 0.375.
(d)
Compute the probability that a student does not have a visa card given that he/she has a master card also, i.e.
as follows:
Thus, the value of
is 0.625.

Step-by-step explanation:
Step 1: Distribute
Step 2: Subtract 20 from both sides
Step 3: Divide both sides by 15
