32% of college students say they use credit cards because of the rewards program. You randomly select 10 college students and ask each to name the reason he or she uses credit cards. Find the probability that the number of college students who say they use credit cards because of the rewards program is (a) exactly two, (b) more than two,
and (c) between two and five inclusive. If convenient, use technology to find the probabilities.
a)
Here, n = 10, p = 0.32, (1 - p) = 0.68 and x = 2
As per binomial distribution formula P(X = x) = nCx * p^x * (1 -
p)^(n - x)
We need to calculate P(X = 2)
P(X = 2) = 10C2 * 0.32^2 * 0.68^8
P(X = 2) = 0.2107
b)
Here, n = 10, p = 0.32, (1 - p) = 0.68 and x = 2
As per binomial distribution formula P(X = x) = nCx * p^x * (1 -
p)^(n - x)
We need to calculate P(X > 2).
P(X > 2) = (10C1 * 0.32^1 * 0.68^9) + (10C2 * 0.32^2 * 0.68^8) +
(10C3 * 0.32^3 * 0.68^7) + (10C4 * 0.32^4 * 0.68^6) + (10C5 *
0.32^5 * 0.68^5) + (10C6 * 0.32^6 * 0.68^4) + (10C7 * 0.32^7 *
0.68^3) + (10C8 * 0.32^8 * 0.68^2) + (10C9 * 0.32^9 * 0.68^1) +
(10C10 * 0.32^10 * 0.68^0)
P(X > 2) = 0.0995 + 0.2107 + 0.2644 + 0.2177 + 0.1229 + 0.0482 +
0.013 + 0.0023 + 0.0002 + 0
P(X > 2) = 0.9789
3)
Here, n = 10, p = 0.32, (1 - p) = 0.68, x1 = 2 and x2 = 5.
As per binomial distribution formula P(X = x) = nCx * p^x * (1 -
p)^(n - x)
We need to calculate P(2 <= X <= 5)
P(2 <= X <= 5) = (10C2 * 0.32^2 * 0.68^8) + (10C3 * 0.32^3 *
0.68^7) + (10C4 * 0.32^4 * 0.68^6) + (10C5 * 0.32^5 * 0.68^5)
P(2 <= X <= 5) = 0.2107 + 0.2644 + 0.2177 + 0.1229
P(2 <= X <= 5) = 0.8157
