Option B
Probability of drawing yellow marble followed by a red marble is
<em><u>Solution:</u></em>
Given that a bag containing 12 yellow marbles, 16 red marbles, and 15 green marbles
So total number of marbles = 12 + 16 + 15 = 43
To find: probability of drawing yellow marble followed by a red marble if the first marble is not replaced
<em><u>The probability of an event is given as:</u></em>
<em><u>probability of drawing yellow marble followed by a red marble if the first marble is not replaced:</u></em>
First we pick up yellow marble.
Number of favorable outcomes = 12 yellow marbles
Total number of possible outcomes = 43 marbles
Now we have to pick red marble
But first marble is not replaced
So we have 43 - 1 = 42 number of possible outcomes
Favorable outcomes = 16 red marbles
So probability of drawing yellow marble followed by a red marble is:
Thus probability of drawing yellow marble followed by a red marble is
Answer:
There are total 5 layers.
Step-by-step explanation:
A multi-layer cake is in the shape of a right cylinder.
Height of the cake is = 20 cm
Radius is = 10 cm
Each of the cake layers has a volume of approximately 1,250 cm³.
Means, the volume of 1 cylindrical layer is 1250 cubic cm with radius as 10 cm and we have to find the height.
Volume of the cylinder is given as:
h = 3.98 or approximately height of 1 layer is 4 cm.
As the cake's height is 20 cm so, there are layers in the cake.
Answer: There are 5 layers in the cake.
