Question

Q13. There are 10 marbles in a box with numbers from Ito 10 marked on each of them.
i) What is the probability of drawing a marble with number 3?​

Answer 1

Answer:

1/10 = 0.1

Step-by-step explanation:

number of marbles in box = 10

the number are = 1,2,3,4,5,6,7,8,9,10

the outcome probability of marble 3 = 1

• probability = outcome cases ÷ total cases
• probability = 1 ÷ 10 = 0.1 (answer)

Answer 2

Total outcomes = 1,2,3,4,5,6,7,8,9 and 10

Favourable outcomes = 2,3,5 and 7(Prime no.s from 1 to 10)

Probability of getting a prime number marble =No. of favourableoutcomes/No. of total outcomes

= 4/10 = 2/5
