Answers
Answer:
Number of times a head turns up = 10
Number of times a tail turns up = 10
Probability of getting a head in a trial =
S{H,T}
P(H) = Number of favourable outcomes
_________________________ = 10/2 = 5/1 (or) 5
Total number of outcomes
Probability of getting a tail in a trial =
S{H,T}
P(T) = Number of favourable outcomes
_________________________ = 10/2 = 5/1 (or) 5
Total number of outcomes
Step-by-step explanation:
Don't follow the same number
You could get any number from tossing coin
Ok anyways this is my answer
Hope this helps
Given : Toss a coin 20 times and Record the observations
To Find : Number of times a head turns up
Number of times a tail turns up
Probability of getting a head in a trial
Probability of getting a tail in a trial
Solution:
Tossed a coin 20 times ,
Results are as follows
H = head , T = Tail
S.No S.No
1 T 11 H
2 T 12 T
3 H 13 H
4 T 14 T
5 H 15 T
6 H 16 H
7 H 17 H
8 T 18 T
9 H 19 T
10 H 20 H
Number of times the coin is tossed = 20
Number of times a head turns up = 11
Number of times a tail turns up = 9
Probability of getting a head in a trial = 11/20 = 0.55
Probability of getting a tail in a trial = 9/20 = 0.45
