Question

Two coins are tossed simultaneously. The probability of getting at least one head is

• A. $\dfrac{1}{4}$
• B. $\dfrac{1}{2}$
• C. $\dfrac{3}{4}$
• D. 1

Hint:

List all outcomes to count favorable events in probability problems.

Answer 1

The Correct Option is C

Problem:
Two coins are flipped. Determine the probability of obtaining at least one head.

Solution:
Possible outcomes:
- HH (Head, Head)
- HT (Head, Tail)
- TH (Tail, Head)
- TT (Tail, Tail)
Total outcomes: 4

Favorable outcomes (at least one head):
- HH
- HT
- TH
Favorable outcomes count: 3

Probability Calculation:
\[\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{3}{4}\]

Answer:
The probability is \(\frac{3}{4}\).
