Question

Probability is the ratio of the favourable cases to the total number of equally likely. The scale of the probability is from 0 to 1,i.e.,0≤P(E)≤1. Probability scale is starting at 0 (impossible) and ending at 1 (certain).Answer the following questions: (i) What is the probability of choosing A vowel from the alphabets? (ii) In a school, only 3 out of 5 students can participate in a competition. What is the probability of the students who do not make it in the competition? (iii)A glass jar contains 6 red, 5 green,4 blue and 5 yellow marbles of the same size. Hari takes out a marble from the Jar at random. What is the probability that the chosen marble is of red colour? (iv) Find the probability of getting a doublet when two dice are thrown simultaneously?​

Answer 1

Answer:

a) 1 / 26

b) 2 / 5

c) 6 / 20

d) 12 / 72

Answer 2

Answer:

(1): 1/26

(2): total students = 5

3 students out of 5 students can participate in a competition

so , 5 - 3 = 2

2 students participate in a competition.

Probability (participate students) =number of favourable outcomes /total outcomes = 2/5

or P(not make in it competition) = 3/5

(3) probability (red marble) = 6/20

total marbles = 20
