Question

2. A coin is tossed 100 times and the following outcomes are recorded
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:

a) P(Head) = 9/20

   P(Tail) = 11/20

b) Sum of probabilities = 1

Step-by-step explanation:

a)

To find probability of al outcomes, we use the formula:

$P(event) = \frac{Favourable}{Total}$

where:

• 'favourable' denotes number of favourable cases

• 'total' denotes total number of cases.

So,

$P(Head)=45/100=9/20$

$P(Tail)=55/100=11/20$

b)

Sum of all outcomes = P(Head) + P(Tail)

= 20/20

= 1
