x	P(x)
0	0.2
1	0.1
2	0.3
3	0.2
4	0.2

• In blank #2 enter the standard deviation for the number of computers sold.(Round your answer to 2 decimal places and enter your answer as 0.12 and not .12.)
• In blank #3 enter the probability the store will sell less than 2 computers in a day. (Round your answer to 1 decimal place and enter your answer as 0.1 and not .1.)
