- Probability of Obtaining not more than 3 Heads when two coins are tossed:
The total number of possible outcomes when two unbiased coins are tossed is 4 (HH, HT, TH, TT). Out of these 4 outcomes, the number of outcomes with not more than 3 heads is 3 (HH, HT, TT).
- Calculating the Probability:
To find the probability of obtaining not more than 3 heads, we need to calculate the probability of these 3 outcomes and add them together.
- Probability of getting HH:
- Since each coin has 2 possible outcomes (head or tail), the probability of getting HH is 1/4.
- Probability of getting HT:
- Similarly, the probability of getting HT is also 1/4.
- Probability of getting TT:
- The probability of getting TT is 1/4 as well.
- Adding the Probabilities:
To find the total probability of not getting more than 3 heads, we add the probabilities of the individual outcomes:
1/4 (HH) + 1/4 (HT) + 1/4 (TT) = 3/4
- Therefore, the probability of obtaining not more than 3 heads when two unbiased coins are tossed is 3/4 or 75%.
