The numbers 1 to 10 are written on sheets of paper and placed in a hat. If one sheet of paper is selected at random then find the following:
The probability (the nember is greater than 3) = 7/10
A. 1/10
B. 3/10
C. 8/10
D. 7/10
The odds the number is a 9 = P(9)/P(not 9)=(1/10)/(9/10)= 1:9
A. 1:9
B. 1:10
C. 1:11
D. 1:1
The probability (the number is odd OR greater than 3= = 5/10+7/10-3/10=9/10
A. 9/10
B. 7/20
C. 12/10
D. 3/10
The probability (the number is odd AND less than 5)=
P(odd)*P(<5|odd) = 5/10*2/10 = 1/10
A. 9/10
B. 7/10
C. 1/5
D. 4/5
