1)T =T/F
F =T/F
2)T =T/F
F =T/F
3)T =T/F
F =T/F
4)T =T/F
F = T/F
16 different combos.
b) Determine the probability that student will get four correct
1/2 chance of getting each correct so 1/2 x 1/2 x 1/2 x1/2 (4 questions, 4x)= 1/16
c) Determine the probability that student will get three questions correct by guessing.
This one i kept getting 1/8 i might be solving it the wrong way but I followed the same pattern as part b.
