Question

NEED FULL EXPLANATION!!

Answer 1

Answer:

Step-by-step explanation:

This is a typical probability question where there is a large number of possible outcomes to be considered.

That suggests an approach where we look at the probability of it not occurring.

For that to happen, we have to have 5 coins all landing heads up. The probability of that happening is (1/2)5=1/32.

From this,  we can deduce the probability of that not happening (i.e. there being at least one tail) is  1−1/32=31/32.

Answer 2

A COIN IS TOSSED 5 TIMES.

A COIN IS TOSSED 5 TIMES.FIND THE PROBABILITY OF GETTING AT LEAST 1 TAILED

• So we can see that the probability of all tails in 5 throws is 132 . We can say that the probability of getting at least one head =1− probability of one head. So the required probability by putting value is 1−132 . Hence the correct option is (d) 3132 .

hope it help
