Chicken Beef Total
Rice 20 10 30

Pasta 40 30 70

Total 60 40 100

Place given information into the chart...Total customers who like rice is 30 and 20 of the like chicken. This means the other 10 (30-20 = 10) must like beef. 60 customers liked chicken means column for chicken has a total of 60. Subtract and find how many like pasta 40 (60 -20 =40)...
Is this enough help or do you need clarification on the second problem?

Answer:3/8

Step-by-step explanation:

Total number of women with ages from 15 to 54years (15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54)= 40

Total number of women with age 40 years and above = 15

Probability of picking a mother of age greater than 40 = 15/40 which is equal to 3/8.
