Isla flipped a coin 30 times. the coin landed heads up 9 times and tails up 21 times.

part a: based on the results, what is the experimental probability of the coin landing heads up? show your work. (5 points)

part b: what is the theoretical probability of the coin landing heads up? show your work. (5 points)

a) 0.3 and b) 0.5

Step-by-step explanation:

Since we have given that

Total number of times Isla flipped a coin = 30

Number of times head comes = 9

Number of times tail comes = 21

So, Based on the results,

Experimental probability of the coin landing heads up is given by

And we know that the each event of fair coin is 50%

And the theoretical probability of the coin landing heads up is given by

Hence, a) 0.3

b) 0.5
