Answer:
1/4
Step-by-step explanation:
coins have 2 sides, tails and heads, so for it to land on tails is a 1/2 chance. Dice have 6 sides and 1,3,5 are all odd so its a 3/6 chance. Simplify 3/6 to 1/2 and multiply by 1/2 to get 1/4. im not sure, its my guess.

Answer:
0.2983
Step-by-step explanation:
Let X be the reading on thermometer. Given that X is N(0,1)
We are to find the probability that a randomly selected thermometer reads between negative 0.12 and 1.02
Reqd probability =
.
Since this x is already normal std variable x=z
i.e. reqd prob = 
Hence answer is 0.2983
