Hello!
First, let's write the possible options:
Dice: 6 different results.
• 1, 2, , 4, 5, 6.
Spinner: 4 different results.
• A, B, C, D.
Knowing it, let's solve each alternative of your exercise:
a. 1 and A
In the dic, we have 6 possible results and we want a specific number. SOo, we can write it as 1/6.
In the spinner, we have 4 possible results and we want a specific one too. So, we have 1/4.
Now, remember he r"and" rule: when we consider two events happening simultaneously, we must multiply their probabilities.
Solving:
b. odd score and B.
We'll solve it in a similar way.
We have three possible odd numbers (1, 3, 5) in a total of 6 options. So, 3/6 = 1/2.
For the spinner, the reasoning will be the same: 1/.
Let's calculate:
c. number less than 5 and a consonant.
In a dice, we have four numbers less than 5: 1, 2, 3,4.
In the spinner, there are 3 consonants (B, C, D).
Let's calculate:
