Explanation / Answer
1.
Possible cases => [h,h] [h,t] [t,t] [t,h]
Favourable outcomes = 2
possible outcomes = 4
P(one time it will be heads and one time it will be tails) = 2/4=1/2
2.
Possible cases => [h,h] [h,h] [t,t] [t,h]
Favourable outcomes =[t,t] = 1
possible outcomes = 4
P(both will land with tails up) = 1/4=1/4
