For #70a, b I know I have to use the complement like
1- (p(all four people with no good blood)) but do I multiply each probability or add them?

For #66 not sure how begin this one

For #63 I feel as if i don't have enough info to start with.

For # 29,29b I get values that are way off the correct answers,
like a) 138783/469491 b) .2965/(107632/156499) ...
i'm probably adding the wrong values. theres just a lot to choose from.

For #39 I would think the answer would just be 70% because its given but no its wrong.

=========================
39 .8235
29 a).4979 b).5144 c).7443 d).4399 e).6894
63 a).216 b).936 c).648
66 .5952
70 .8704

Can you please say which formula you're using if any. It's hard for me to understand problems with percents. We have just covered Bayes rule, conditional probability, multiplicative rule, additive rule, complement and independence.
