Roll two die simultaneously 20 times. Note down the the outcomes on both the die each time on your register. Now add the outcomes obtained on two die every time you rolled them.
Find the probability of getting the sum
a) Less than 7 (b) more than 9
This is an experiment that YOU have to perform
Rolling two dice = 36
So , if they are rolled 20 times = 36 × 20 = 720
a) 30/720
b) 52/720
Am i right ????
