Question

2. A coin is tossed 100 times and the following outcomes are recor
Head:45 times
Tails:55 times from the experiment
a) Compute the probability of each outcomes.
b) Find the sum of probabilities of all outcomes.​

Answer 1

Answer:

9/20, 11/20 and 1

Step-by-step explanation:

head = 45/100 =9/20

tails =55/100=11/20

sum = 9/20+11/20=20/20=1

Answer 2

number of times coin is tossed -----> 100

heads -----> 45

tails --------> 55

a) heads -----> 45 / 100 => 9/20

tails -----> 55/100 => 11/20

b) 45 + 55 /100 = 100 /100 = 1

9/20 + 11/20 = 20/20 = 1
