You are writing a test of 40 objective type questions. Each question carries 1 mark. What is the probability of marks you may get to be in multiple of 5?
Answers
Answer:
P(getting a multiple of 5) =\dfrac{1}{5}=51 .
Step-by-step explanation:
The number of objective type questions = 40
To find, the probability of marks you may get to be in multiple of 5 = ?
Total number of possible outcomes = 40
The factors of multiple of 5 are:
5, 10, 15, 20, 25, 30, 35 and 40
The number of favourable outcomes = 8
∴ Probability =\dfrac{The number of favourable outcomes}{Total number of possible outcomes}=TotalnumberofpossibleoutcomesThenumberoffavourableoutcomes
P(getting a multiple of 5) = 8/40
Answer:
9 / 41.
Step-by-step explanation:
we can obtain a marks from 0 - 40 which has 41 possibilities in total.
multiples of 5 from 0 - 40 are 0, 5, 10, 15, 20, 25, 30, 35, and 40. which are 9 outcomes in total.
probability of getting multiples of 5 as a mark
= ( No. of favorable outcomes) / ( total No. of possibilities)
= 9 / 41.
