Multiply all the sides , 5x3x6 + 3x7x16
Answer:
2/3
Step-by-step explanation:
Given that a six sided die with sides labelled with numbers 1,2,3,4,5 and 6 is rolled once.
Since die is said to be equally likely for each number, die is unbiased
P(1) = P(2)=...=P(6) = 1/6
For a number greater than 2, we must not include 2 and hence numbers can be 3 or 4 or 5 or 6
Probability of rolling a number >2 = Probability of rolling 3 or 4 or 5 or 6
= P(3)+P(4)+P(5)+P(6)
= 1/6+1/6+1/6+1/6
=4/6
=2/3
Required probability = 2/3
Answer: -4 will be the answer
Step-by-step explanation:
1)
Let x=larger number
y=smaller number
x+y=59
x-y=13
Now adding these two equations we get
2x=72
x=36
Now as x-y=13
y=x-13=36-13=23
y=23
Therefore the larger number is 36 and the smaller number is 23
(or else u could also write)
The numbers are 36 and 23
---------------------------------------------
2)
Let x=first number
y=Second number
x+y=15
2x-y=6
Now adding these two equations we get
3x=21
x=7
Now as x+y=15,
y=15-x=15-7=8
y=8
Therefore the first number is 7 and the second number is 8
-------------------------------------------
3)
Let x=Larger number
y=smaller number
x-y=3
x-3y=-11
Now on subtracting these two equations we get
2y=14
y=7
Now as x-y=3,
x=y+3=7+3=10
x=10
Therefore the larger number is 10 and the smaller number is 7
