Answer:
0.262144 = 26.2% of getting all the 6 questions correctly.
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 = 6 multiple choice questions
x = Number of successes required = 6 (we want to get it all right.
p = probability of success = 0.8 (80% chance of getting any individual question right; 0.8 probability of getting each question correctly)
q = probability of failure = 1 - 0.8 = 0.2
P(X = 6) = ⁶C₆ (0.8)⁶ (0.2)⁶⁻⁶ = 1(0.262144)(1) = 0.262144
Answer:
£ 14430
Step-by-step explanation:
Costing price = £13000
Increase = 11% of 13000
=> 11/100 × 13000
=> 11 × 130
=> £ 1430
Increased Price = 13,000+1430
=> £ 14430
