Answer:
d) The probability spinner will land on black all three times is 1/8
Step-by-step explanation:
The probability of landing on black = 1/2
The probability of landing on red = 1/3.
Now, if the spinner is spun 3 times.
The probability it will land on black all three times
= [tex]\textrm{ (The probability of landing on black)}^3[/tex]
= [tex]\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{2 \times 2 \times 2 } = \frac{1}{8}[/tex]
Hence, the probability spinner will land on black all three times is 1/8.
