Amultiple choice test has five questions each with 5 possible answers. find the probability of guessing the correct answers to all of the questions

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%

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
