Two unbiased coins are tossed. The probability of obtaining one head a...
Explanation:
When two unbiased coins are tossed, there are four possible outcomes: HH, HT, TH, and TT. Out of these, only two outcomes have one head and one tail: HT and TH.
Therefore, the probability of obtaining one head and one tail is the ratio of the number of favorable outcomes to the total number of possible outcomes.
Solution:
Number of favorable outcomes: 2 (HT and TH)
Total number of possible outcomes: 4 (HH, HT, TH, and TT)
Probability of obtaining one head and one tail:
= Number of favorable outcomes / Total number of possible outcomes
= 2 / 4
= 1/2
Hence, the correct answer is option B: 2/4.

Probability of obtaining one head and one tail:
= Number of favorable outcomes / Total number of possible outcomes
= 2 / 4
= 1/2

Total outcomes = ( hh,tt,ht,th)=4
one head =1/4 and (+) one tail = 1/4
1/4 + 1/4 = 2/4
one head =1/4 and (+) one tail = 1/4
1/4 + 1/4 = 2/4
