Answer:
P(X > 2) = 0.6687
P(2 < X < 5) = 0.4821
Step-by-step explanation:
This is a binomial distribution problem
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = sample size = 10
x = Number of successes required = more than 2, then between 2 and 5.
p = probability of success = probability that a college student will say they use credit cards because of the rewards program = 0.32
q = probability of failure = 1 - 0.32 = 0.68
For more than 2
a) P(X > 2) = 1 - P(X ≤ 2) = 1 - [P(X=0) + P(X=1) + P(X=2)] = 1 - [0.0211392282 + 0.09947872095 + 0.21066082083] = 0.66872123002 = 0.6687
For between 2 and 5 exclusive
P(2 < X < 5) = P(X=3) + P(X=4) = 0.26435867712 + 0.21770714587 = 0.482065823 = 0.4821

Answer:
The estimated taken to drive downtown using App is 38.4 minutes
Step-by-step explanation:
Given as :
The initial time taken to drive downtown = i = 48 minutes
The percentage error of time = r = 20%
Let The estimated time using app = t min
Let the time = 1 min
<u>Now, according to question</u>
The estimated time using app = The initial time taken to drive downtown ×
Or, t minutes = i minutes ×
Or, t = 48 minutes ×
Or, t = 48 minutes ×
Or, t = 48 minutes ×
∴ t = minutes
I.e t = 38.4 minutes
Or, The estimated time using app = t = 38.4 min
Hence, The estimated taken to drive downtown using App is 38.4 minutes Answer
