Answer:
P(green or orange) = 4/7
Step-by-step explanation:
We need to know how many tennis balls there are
total = 15 yellow+ 5 orange+ 15 green
= 35 balls
Probability of green or orange tennis ball is the sum of the green and orange tennis balls over the total balls
P(green or orange) = (green + orange)/total
= (15+5)/35
=20/35
=4/7
There are 659 blocks
<em><u>Solution:</u></em>
The number in ones place is 9
Let's denote number in the tens place with x
The number in the hundreds place is one more then the tens place
Therefore,
The number in hundreds place is 1 + x
Those two numbers equal 11
Which means tens place number and hundreds place number sums up to 11
tens place + hundreds place = 11
x + 1 + x = 11
2x = 11 - 1
2x = 10
x = 5
Thus number in tens place = x = 5
Number in hundreds place = 1 + x = 1 + 5 = 6
The number is represented as:
Number = (Number in hundreds place)(number in tens place)(number in ones place)
Number = 659
Thus 659 blocks are there
