Could anybody help with part a and b ??

The answer to part A is the last option ( at the bottom) because we know that he bought one notebook, but we don't know how many pens he bought. The answer to part b would be 12 pens. To get the part b answer you simply solve for the variable p in the equation. Hope this helps! Have a nice day!

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2
