1st question search in this pdf.

Tip: Type first sentence of any question in google more often than not you'll get something. 

Pro tip: Attempt all these by yourself and only refer solutions if you're stuck somewhere.

1) i) Probability of surviving first inspection = 1 - probability of being rejected by the first inspection (ie 1-0.1)

0.9 * 0.08 = 0.072 

ii) 0.9 * 0.92 * 0.12 = 0.09936 

2) i) (3/5) * (2/6) = 0.2 

ii) (2/5) * (4/6) = 0.267

iii) The possibilities are: aspirin + thyroid, aspirin + laxative, thyroid + aspirin, thyroid + laxative

So 2/5 * 3/6 + 2/5 * 1/6 + 3/5 * 3/6 + 3/5 * 1/6 = 0.667 

3) 0.6 * 0.3 * 0.1 = 0.018 

I don't take any responsibility for any answers. I've been in medical school for the past few years. :itsok:

Salam Aleykoom,

I suggest you to use the formula for conditional probabilities, which is written as: 74cbddb93db29a62d522cd6ab266531ae295a0fb which means:

"The probability of A happening, given B has happened, is equal to the probability of both A and B happening divided by the probability of B happening."

I also suggest you not to take too much heed to Basim Ali's answers ;)

Good luck for your assignment!

Wa Salam.
