Question

I have two coins. One is fair, and has a probability of coming up heads of.5. \text {The second is bent, and has a probability of coming up heads of} .75The second is bent, and has a probability of coming up heads of.75. If I toss each coin once, what is the probability that at least one of the coins will come up tails?

Answer 1

The probability that at least one of the coins will come up tails is 0.625

Given:

The probability of getting heads on fair coin = 0.5

The probability of getting heads on bent coin = 0.75

Step-by-step explanation:

The probability of getting tails on at least one coin is given by the formula:

P = 1 - Pₐ

Where, Pₐ = Probability of getting both heads

P = 1 - (0.5 × 0.75)

P = 1 - 0.375

∴ P = 0.625
