Question

1. A coin is tossed 300 times and we get
head: 136 times and tail: 164 times.
When a coin is tossed at random, what is the probability of getting (1) a head. (11) a tail?

2. Two coins are tossed simultaneously 200 times and we get
two heads: 58 times; one head: 83 times: O head: 59 times.
When two coins are tossed at random, what is the probability of getting (1) 2 heads.
(ii) 1 head, (111) O head?

4. In a survey of 100 ladies it was found that 36 like coffee while 64 dislike it.
Out of these ladies, one is chosen at random. What is the probability that the chosen lady
(1) likes coffee, (ii) dislikes coffee?
​

Answer 1

Step-by-step explanation:

Probability for getting Head =136/300 =34/75

Probability of getting tail =164/300 =41/75

Probability of getting 1 head =83/200

=0.415

probability of getting 0heads=59/200

=0.295

no. of two heads =83+59=142

=200-142

=58

probability of getting 2heads =58/200

=0.29

The probability of getting ladies who likes coffee=36÷100=9÷25

The probability of getting the ladies who dislikes coffee=64÷100=16÷25

the one who likes coffee=

9/5

the one who dislikes coffee=

16/25
