6 answers

Prob(Right) = 1/2

In 5 problems you want RRRRR
prob(RRRRR) = (1/2)^5 = 1/32
2*2*2*2=2^5..... By multiplying 2 Five times and and the root number 5... the probability of answering ll of them correct is 1/23.

: )
The probability of guessing correctly on all of five true-false questions is 1/5. True or False
I’m not sure
I'm done taking the test and the right answer was actually 1/32..
