Question

A coin is tossed 500 times with the following frequencies of two outcomes:
head = 245 times
tail = 255 times

What is the probability of getting a head in the next throw?

• A. 0.49
• B. 0.5
• C. 0.51
• D. 0.45

Answer 1

The correct option is A

0.49

Since the coin is tossed 500 times, the total number of trials is 1000.
The number of times a head comes up, is 245.

$\text{Probability of getting a head}=\frac{\text{Number of times head comes up}}{\text{Total number of trials}}=\frac{245}{500}=0.49$
