zmey [24]

Answer:

The probability is 0.8

Step-by-step explanation:

  • if u see the table clearly, there are 30 houses in total with 2 bathrooms.
  • by the general definition of probability,

probability of an event P =\frac{Number of desirable observations}{total number of observations}

  • so, here 30 will be the denominator in the above formula(by definition).
  • from the table, in the 3rd column and 2nd row (desirable box) i.e, the one which represents 2 bathrooms and 3 bedrooms, has the entry as 24.
  • so, the numerator for above given formula will now become 24.

therefore probability P=\frac{24}{30} =\frac{8}{10} =0.8

  • So, the probability is 0.8.

dalvyx [7]

The quantity of sugar required for 2/4 of the recipe is 1/3 cups

<h3>How to solve fraction?</h3>

let

  • x = quantity of sugar needed

Ratio of sugar to recipe

2/3 : 1 = x : 2/4

2/3 ÷ 1 = x ÷ 2/4

2/3 × 1/1 = x × 4/2

2/3 = x × 2

2/3 = 2x

x = 2/3 ÷ 2

x = 2/3 × 1/2

= 2/6

x = 1/3 cups

Therefore, the quantity of sugar required for 2/4 of the recipe is 1/3 cups
