Question

when you flip a biased coin the probability of getting a tail is 0.3 how many times would you expect to get tails if you flip the coin 160 times

Answer 1

Answer:

You can expect to get tails 48 time's.

Step-by-step Explanation :

Given : when you flip a biased coin the probability of getting a tail is 0.3

To find : how many times would you expect to get tails if you flip the coin

160 times = ?

So ,

According to given conditions,, .

When we flip a biased coin the probability of getting a tail is 0.3 i.e ther is 30% chance of getting tail and 70% chance of getting head .

I.e. 1 flip --------------- 0.3 probability

160 flip ----------. ?

Just simply doing cross multiplication,

160 × 0.3 = 48

So you can expect to get tails 48 time's.
