Given the statement:
A dice is rolled 360 times and the results are recorded as follows: 60 ones 58 twos 70 threes 74 fours 38 fives and 60 sixes
Determine the experimental probability of rolling a two or a three.
Solution:
We must first add the total number of twos and threes rolled.
=58 + 70
= 128
Now we divide 128 by 360 since it is the total number of times that the dice is rolled.
= 128/360
= 0.36 or 36%
Final answer:
The probability of rolling a two or three is 0.36 or 36%
