Answer: 1/16 = 0.0625
Step by step solution:
The probability (P) of an event happening is
[tex]P=\frac{Numbe\text{r of ways it can happen}}{Total\text{ number of outcomes}}[/tex]
When Bob flips the coin he has two options, head or tail. The probability that it lands tails up is:
[tex]P=\frac{1}{2}[/tex]
The probability that the pointer stops on the letter R is:
[tex]P=\frac{1}{8}[/tex]
Now, the probability of both events happening (tails up and pointer on R) is:
[tex]P=\frac{1}{2}\times\frac{1}{8}=\frac{1}{16}=0.0625[/tex]
