Question

An unbiased dice was rolled 800 times. The frequencies of the various outcomes are
given in the table below:
Outcome: 1
2
3
5
200 100
Frequency: 150
75 125 150
When the dice is rolled, the probability of getting a number which is a perfect square
is​

Answer 1

Answer:

Now, 1 and 4 are perfect squares among the outcomes 1, 2, 3, 4, 5 and 6.

∴ Number of trials of getting a number which is perfect square on the dice

= Frequency of getting 1 or 4 on the dice

= 150 + 75

= 225

So, P(Getting a number which is perfect square) = P(E) = Number of trials of getting a number which is perfect squareTotal number of trials=225800=9/32

Thus, the probability of getting a number which is a perfect square is 9/32.
