Answer 1

Given :  Liz flipped a coin 30 Times.  Coin land Heads up 12 times & Tails 18 times

To find : Probability based on Experiment

Solution:

Coin Flipped number of times  =  30

Head turned up  = 12

Tail Tuned up  = 18  

Probability of Head  =  ( number of times head turned up )/ (Total number of times coin flipped)

= 12/30

= 2/5

= 0.4

Probability of Tail  =  ( number of times Tail turned up )/ (Total number of times coin flipped)

= 18/30

= 3/5

= 0.6

Probability Head = 2/5  = 0.4

Probability Tail = 3/5 = 0.6
