A survey of patients at a hospital classified the patients by gender and blood type, as seen in the two-way table. Gender Blood Type Male Female
Based on the data, what percent is the probability that a female patient will have type-O blood? Round your answer to the nearest tenth of a percent.

Gender

Blood Type
Male Female TOTAL
A 105 93 198
B 99 84 183
O 160 140 300
AB 15 18 33
TOTAL 379 335 714

41.8%

Step-by-step explanation:

Here, we want to find the probability. Probability is essentially just (# times the specific event will occur) / (# times any general event will occur).

The specific event here is getting a female patient with blood type O, while the general event is just choosing a female patient.

There are 140 female patients with type O blood and there are a total of 335 females. So, our probability is:

(140 / 335) * 100 ≈ 41.8%

Step-by-step explanation:

Step 1:  We need to find the percent of female patient with type-O blood

Total Females = 335

Total Females with type-O blood = 140

Percentage = 140 / 335

Percentage ≈ 0.418 * 100

Percentage ≈ 41.8%

sorry, i can't understand your question. will later if you describe more clearly!
