The second question:- A box contains 6 white balls, 7 black balls, and 2 red balls 1- When two balls are drawn in a row without rewinding, calculate the probability that the drawn balls are red. 2- When two balls are drawn in a row with rewind, calculate the probability that the drawn balls are white. Calculate the probability that 3 balls are drawn of different colors when drawn without rewind . 3- Calculate the probability that (2 balls) drawn are white and (2 balls) drawn are black with rewind. o11:27 /
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

1- When two balls are drawn in a row
without rewinding, calculate the probability
that the drawn balls are red.
2- When two balls are drawn in a row
with rewind, calculate the probability
that the drawn balls are white. Calculate
the probability that 3 balls are drawn of
different colors when drawn without rewind
. 3- Calculate the probability that (2 balls)
drawn are white and (2 balls) drawn are
black with rewind.
