If u flipa coin twice then sample space={HH,TT,HT,TH}
Answer:
6/12
1/2
Step-by-step explanation:
First, we need to find how many multiples of three there are, and how many numbers less than three there are on a 12 sided die.
Multiples of 3: 3, 6, 9 ,12
Less than 3: 2, 1
When calculating the probability of rolling a number, the actual number is arbitrary- instead, you need to know how many of numbers exist to fit the requirements. In this case, it's 6 total. Since there's 12 possibilities on a 12 sided die, the probability would be 6 out of 12. You could also simplify the fraction, but both are equivalent.
I hope this helps!

Answer:
4
Step-by-step explanation:
Simplify x and y by rationalising the denominator of both
To rationalise the denominator multiply the numerator/ denominator by the conjugate of the denominator.
The conjugate of 2 + 
is 2 -
The conjugate of 2 - is 2 +
x = 
= 
= 2 -
y = 
= 
= 2 +
Thus
x + y = 2 - + 2 + = 4
