Probability

Answer 1

probability of getting exactly 2 heads=2/6=1/3
probability of getting at least two heads=3/6=1/2

Answer 2

Answer:

(i) 1/4

(ii) 1/2 OR 0.5 or 50%

(I'm only doing the first question, sorry)

Step-by-step explanation:

(i) You have to make a sample space. I know this was meant to be for helping other people, but my phone's out of battery and I'm using my laptop.

Anyways, the reason for this is that three coins are being tossed. The only way you can get an exact double-head is if you get a "h,h,t" or likewise combination.

(ii) Again, you have to make a sample space for this. The only qualification you need for this is to have at least two heads. Therefore, you can also include a "h,h,h" combination. We can also count our answer for the (i) part in this, making it 2/4 // 1/2 // 0.5
