Question

There are 10 slips numbered 1 to 10.one slip is chosen at random. what is the probability that number on slip is
1) greater than 7
2) odd number
3) Even number less then 6.​

Answer 1

Answer:

Probability = favorable outcomes/total outcomes

1. Favorable outcomes: 8, 9, 10 ⇒ 3 outcomes

Total outcomes = 10 (total slips)

⇒ P(greater than 7) = 3/10 = 0.3

2. Favorable outcomes: 1, 3, 5, 7, 9 ⇒ 5 outcomes

⇒ P(odd number) = 5/10 = 1/2 = 0.5

3. Favorable outcomes: 2, 4 ⇒ 2 outcomes

⇒ P(even no. less than 6) = 2/10 = 1/5 = 0.2
