b. How many points are there in the sample space
c. Find the probability that a tail is flipped and a 3 is selected
d. Find the probablity that a head is flipped or a number less than 3 is selected.

You can put this solution on YOUR website! A coin is flipped and then a number from 1 to 4 is selected at random from a bag.
a. construct a tree diagram showing all the possible outcomes
h: 1,2,3,4
t: 1,2,3,4
-------------------------------
b. How many points are there in the sample space::2*4 = 8
-----------------------------------------------------------------
c. Find the probability that a tail is flipped and a 3 is selected: 1/8
----------------------------------------------------------------------
d. Find the probability that a head is flipped or a number less than 3 is selected.:: 2/8 = 1/4
-------------------------------
e. Find the probabiliiy that a head is flipped and an even number is selected:
2/8 = 1/4
