# In the example of tossing two quarters, what is the coin A is a head? that coins A and B are either both heads or both tails?

To determine

To find:

If we throw the two dices 4 times the find the following probability:

• The probability of getting at least one head?
• That Coin A is head?
• Those coins A and B are either heads or both tails?
Explanation

Given:

We toss two coins 4 times.

Formula used:

P(E) =The number of favourableoutcomes in (E)The total number of outcomes in (S)

Concept used:

Let’s assume that E represents the no. of favourable event and S represents to no. of events in sample space S.

Calculation:

Sample Space: {HH, HT, TH, TT}

• The probability of getting at least one head?

Possible outcomes with at-least one tails are = {HT, TH, and TT}

Probability of getting at-least one tails = 34
