Question

Two coins are tossed simultaneously 500 times. If we get two heads 100 times one
head 270 times and no head 130 times, then find the probability of getting –
(1). One head.
(2). 2 Tail.
(3). One or more than one head.
(4). One tail.
(5). No tail.

Answer 1

Step-by-step explanation:

one head :-

probability : number of favourable outcome/ number of total outcomes

= 270/500

=5 .19 or 27/50

two tails :-

=130/500

=13/50

one or more than one head :-

= 100+270/500

= 370/ 500

=37/50

one tail :-

=270 /500

= 27/50

no tails :-

100 /500

= 1/5
