Write each of the numbers 1-10 to on a piece of paper fold up the pieces of paper and put them in a box shuffle and draw one piece note it's number. fold it and replace in the box. repeat the experiment 120times. what is the experimental probability of drawing out: a 1,a 6,an odd number, a prime number ​

1 / 10 ; 1 / 5 ; 5 / 12 ; 2 / 5

Explanation:

Experimental probability is defined as the ratio of the total number of times an event occur to the total number of trials.

In the experiment performed, the total number of trials is the number of times a paper was drawn from the lot, which 120 times.

From the experiment, the following observations were recorded :

X ___ number of times drawn

1 12

2 18

3 13

4 9

5 8

6 24

7 9

8 ___ 12

9 ___ 8

10 ___ 7

Experimental probability = number of times an event occur / total number of trials

Experimental probability of :

P(1) = 12 / 120 = 1 / 10

P(6) = 24 /120 = 1 / 5

P(an odd) = p(1) + p(3) + p(5) + p(7) + p(9)

P(odd) = (12 + 13 + 8 + 9 + 8) / 120 = 50 / 120 = 5 / 12

A prime number = P(2) + p(3) + p(5) + p(7)

P(prime number) = (18 + 13 + 8 + 9) / 120 = 48 / 120 = 2 / 5
