Nick tosses a standard number cube and
spins a spinner. the spinner is divided
into four equal sections colored red, blue,
green, and yellow. what is the probability
that nick rolls an odd number and spins
green?

By standard number cube I'm just gonna assume you mean a die (singular of dice)

A die has 6 sides and the spinner has 4 different sections. Let us find the LCM. 6 x 4 equals 24.

The probability of the spinner to land on green is 1/4 , or 6/24

The probability of the die to land on an odd number is 1/2, or 12/24, since a die has numbers 1-6 on the sides/faces (with 1 number on each face) and the odd numbers are 1, 3, and 5.

And idk if this is correct but.. Try adding 12/24 (2/4 or 1/2) by 6/24 ( 1/4) and it'll be 18/24 (3/4)
