Question

A coin is tossed 600 times with the following frequencies of two outcomes: Head: 250 times, tails: 350 times Find the probability of occurrence of each of these events.​

Answer 1

Answer:

Step-by-step explanation:

Correct option is A)

Two coins are tossed simultaneously for 600 times and the outcomes are as follows :

Two heads : 200

One head : 160

No head : 240

The probability of getting one head is:

P(E)= 600/160

​ = 15/4

​

Answer 2

Given:

A coin is tossed 600 times with the following frequencies of two outcomes: Head: 250 times, tails: 350 times

To Find:

Probability of occurrence of each of these events

Step-by-step explanation:

• As the total number of outcomes are $600$ and probability of an event is $P(E)= \frac{\ Total \ favourable \ outcomes }{\ Total \ outcomes}$
• Probability of occurrence of Head is $P(Head)=\fract{\250}\div {\ 600}=\fract{\ 5}\div {12}$
• Probability of occurrence of Tails is $P(Tails)=350\div 600 = 7\div 12$

The Probability of the events are $5\div 12$ and $7\div 12$ .
