Joe nas to take two quizzes tomorrow. He nas only enough time to study one of them. • The science quiz has 7 true-or-false quest
Nostrana [21]

Answer:

C.

Step-by-step explanation:

Science questions are T/F. That's .5 or \frac{1}{2} chance to get it right.

7 questions. Each with a \frac{1}{2}.

That's (\frac{1}{2})^{7}  

(\frac{1}{2})^{7} = \frac{1}{128} = .0078 = .008 rounded

English questions are multiple choice. 4 choices. That's .25 or \frac{1}{4}

3 questions. Each \frac{1}{4}

That's (\frac{1}{4})^{3}

(\frac{1}{4})^{3} = \frac{1}{64} = .0156 = .016 rounded
