The probability is given by:
[tex]P=\frac{numb\text{er of favourable outcomes}}{\text{total number }of\text{ outcomes}}[/tex]
Therefore:
- The probability of spinning blue is:
Favorable outcomes = 1 (blue color)
Total outcomes = 3 (red, blue, and yellow)
[tex]P(\text{spinning blue)}=\frac{1}{3}[/tex]
- The probability of flipping heads is:
Favorable outcomes = 1 (head)
Total outcomes = 2 (head and tail)
[tex]P(\text{flipping head)=}\frac{1}{2}[/tex]
- The probability of spinning a one is:
Favorable outcomes = 1 (number 1)
Total outcomes = 3 (numbers 1, 2 and 3)
[tex]P(\text{spinning a one)=}\frac{1}{3}[/tex]
Next, the probability of the compound event:
[tex]P(\text{compound event)=}\frac{1}{3}\times\frac{1}{2}\times\frac{1}{3}=\frac{1\times1\times1}{3\times2\times3}=\frac{1}{18}[/tex]
Answer: the probability of the compound event is 1/18
