What is the probability of A and B telling lie Prob of a telling truth equals 80 percent Prob of b telling truth equals 75 percent?

Answer 1

Chance that A told the truth: 0.8 (80%)

Chance that B told the truth: 0.75 (75%)

Chance that A told a lie: 1 - 0.8 = 0.2 (20%)

Chance that B told a lie: 1 - 0.75 = 0.25 (25%)

Chance that both A and B told a lie: 0.2 * 0.25 = 0.05 (5%)

Chance that both A and B told the truth: 0.8 * 0.75 = 0.6 (60%)

Chance that A told a lie and B told the truth: 0.2 * 0.75 = 0.15 (15%)

Chance that A told the truth and B told a lie: 0.8 * 0.25 = 0.2 (20%)
