Answer:
This is not likely
Explanation:
When Rachel tossed a fair coin ten times, it is not likely she gets heads every time. This is because on a coin there is an head and a tail.
There is an equal chance of obtaining a tail and an head. i.e there is 1/2 chance of obtaining 10 heads and 1/2 chance of obtaining 10 tails.
Hence, the probability of getting heads after tossing the fair coin 10 times
= 1/2¹⁰ = 1/ 1024
This means Rachel would have to carry out a large amount of trials and the calculation above shows that only 1 trial would succeed out of 1024 trials would give Rachel, heads every time she tossed the fair coin 10 times.
