Question

If a coin is tossed 100 times out of which the outcomes we get are head and 30 times we get tail then the probability of not getting tail is a)5 b)7.5 c)65 d)3.5 with method ​

Answer 1

Answer:

1) Probability of getting a tail is 30/100 (Given)

2) Probability of getting a head is 1 - 30/100 = 70/100

3) Probability of getting no tail (getting head) is 1 - 30/100 = 70/100

Explanation:

A probability of one means that the event is certain. If you toss a coin, it will come up a head or a tail.

So there is a probability of one that either of these will happen.

A probability of zero means that an event is impossible.
