RS Aggarwal Test: Probability - Class 10 MCQ

To determine which of the following cannot be a probability:

- A: 1/3 is a valid probability as it falls between 0 and 1.
- B: 0.1 is also a valid probability, representing 10% likelihood.
- C: 3% can be converted to a decimal (0.03), making it a valid probability.
- D: 17/16 is greater than 1, violating the probability rule (must be between 0 and 1).

Therefore, D: 17/16 cannot be the probability of an event.

Total number of outcomes =52

we have only 1 ace of hearts , so the number of favourable outcomes of E ,

where E is card not an ace of hearts = 51.

 Probability facts.

odd number less than 3 is only 1
so probability=1/6

It is given that

Total number of eggs = 400

Probability of getting a bad egg P(E) = 0.035

Consider x as the number of bad eggs

The formula to find the probability is

P(E) = Number of bad eggs/ Total number of eggs

Substituting the values

0.035 = x/400

By further calculation

35/1000 = x/400

x = 35/1000 x 400

x = 140/10

x = 14

Therefore, the number of bad eggs in the lot is 14.

P = 640/1000 = 0.64

Two coin tossed
Total sample space = {HH, HT, TH, TT}
Sample space for getting atmost one head = {TT, TH, HT}
P(s) = 3/4
