Solution:
(i) Here, total number of trials = 300
Number of heads got = 136.
P(E) = 136300 = 3475
(ii) Total number of trials = 300
Number of tails got = 164
P(E) = 164300 = 4175

Question 2.
Solution:
Number times, the two coins were tossed = 200
Number of times got two heads = 58
Number of times got one head = 83
and number of times got no head = 59
(i) Probability of getting 2 heads : P(E) = 58200 = 29100
(ii) Probability of getting one head : P(E) = 83200
(iii) Probability of getting no head : P(E) = 59200

Question 3.
Solution:
Number of times, a dice was thrown = 100
(i) Number of times got 3 = 18
Probability will be
P(E) = 18100 = 950
(ii) Number of times got 6 = 9
Probability will be
P(E) = 9100
iii) Number of times got 4 = 15
Probability will be
P(E) = 15100 = 320
(iv) Number of times got 1 = 21
Probability will be
P(E) = 21100h

Question 4.
Solution:
Total number of ladies = 100
Number of ladies also like coffee = 36.
Number of ladies who dislike coffee = 64
(i) Probability of lady who like coffee :
