Tiny's Tattoo Parlor sold 389
tattoos this month. 43
of those tattoos were arm tattoos.
Based on this data, what is a reasonable estimate of the probability that the next customer does not get an arm tattoo?
To estimate the probability that the next customer does not get an arm tattoo, we divide the number of tattoos that are not arm tattoos by the total number of tattoos sold.
Number of tattoos that are not arm tattoos = Total tattoos sold - Arm tattoos sold
= 389 - 43
= 346
Probability = Number of tattoos that are not arm tattoos / Total tattoos sold
= 346 / 389
≈ 0.889
So, a reasonable estimate of the probability that the next customer does not get an arm tattoo is approximately 0.889 or 88.9%.
