Question

Help me please I don’t get it

Answer 1

There are 16 outcomes because 4 x 4 equals 16

Answer 2

Part A

There are 16 different outcomes because 4*4 = 16. There are four letters so that's why we multiply those two '4' terms. This is only if we allow repeat letters. If we spun 3 times, then we would have three copies of '4' multiplied together. This idea can be extended on forever.

====================================================

Part B

The 16 different outcomes are:

{H,H} {H,P} {H,E} {H,O} {P,H} {P,P} {P,E} {P,O} {E,H} {E,P} {E,E} {E,O} {O,H} {O,P} {O,E} {O,O}

Each different outcome is in its own set of curly braces.
