This table shows the results of rolling a standard number cube.
What is the approximate experimental probability of rolling a number less than 3?
Answer choices:
19%
17%
26%
33%

Answer 1

1. 42%

2. 33%

Explanation:

1. Relative frequency = Number of successful trials ÷ Total number of trials

plug the numbers in and we get 42/100. 42/100 = 0.42 = 42%

2. Experimental probability = Number of in which the outcome occurs ÷ Total number of trials

plug the numbers in and we get 2/6 = 1/3 = 33%

Answer 2

1) Correct option is C)

A fair coin is tossed 100 times and the head occurs 58 times and tail 42 times.

The experimental probability of getting a head is :

P(E)=

Total outcomes divided by Number of head

58/100 = 29/50 (29/50x100) = 58% (C)

2) 19%​
