Answer:
5/25 or 1/5
Step-by-step explanation:
5 questions, each has 5 possible answers, 5x5=25 each question had 1 correct answer so 5 right answers in the whole test. 5/25 but if u need to simplify, 1/5
Answer: Probability of guessing all 5 correctly: 1/3125 = 0.032%
Step-by-step explanation:
Probability of guessing the first question correctly: 1/5
For that 1/5 of the time when the first question has been guessed correctly, the second question could be guessed correctly 1/5 of the time. So the first two questions could be guessed correctly 1/5 × 1/5 = (1/5)^2 of the time.
Similarly the first three questions could be guessed correctly (1/5)^3 of the time.
and the first four, 1/5)^4 of the time;
and all fives,
(1/5)^5 of the time.
(1/5)^5 = 1/3125 = 0.00032 = 0.032%
