8.33%
Step-by-step explanation:
Given that the quiz has;
A multiple-choice question with 3 possible answers
A multiple-choice question with 4 possible answers
In the first question;
⇒The three choices,each has the probability of 1/3 to be picked
In the second question;
⇒The four choices, each has a probability of 1/4 to be picked
1/4
Finding the probability that both responses are correct will be;
1/3* 1/4 =1/12
As a percentage will be
1/12 * 100= 8.33%
Ответ:
The probability that both responses are correct will be 8.33%.
Given that,
The quiz has; a multiple choice question with 3 possible answers,
And a multiple-choice question with 4 possible answers.
We have to find,
The probability that both responses are correct.
Probability = Incorrect%
According to the question,
The three choices ,each has the probability of
to be picked,
And the four choices, each has a probability of
to be picked.
Then, Finding the probability that both responses are correct will be;
=
= ![\frac{1}{12}](/tpl/images/0243/8400/aba7e.png)
As a percentage will be,
Hence, The probability that both responses are correct will be 8.33%.

Ответ:
a = 35°; b = 50°; c = 85°; d = 30°
Step-by-step explanation:
a = 35° because a + 80 + 65 = 180.
b = 50° because b+ 35 + 95 = 180.
c = 85° because c + 95 = 180.
d = 30° because d + 85 + 65 = 180.
