The probability that she will have two boys will be .
Probability is the ratio of number of favorable outcome to the total number of outcome.
Probability
We have,
Boy-Boy
Girl-Girl
Boy-Girl
Girl-Boy
So,
Total number of outcome
And number of favorable outcome of Boy-Boy
So,
Probability
Probability (Boy-Boy)
Hence, we can say that the probability that she will have two boys will be .

-31/8 converts to -3.875 in decimal form. In the case of negative numbers, 'less than' refers to numbers further from zero. Therefore, -3.92 is 'less than' -31/8.
To answer this question, we first need to convert -31/8 into decimal form. Doing this, we get -3.875.
Now we can compare -3.875 and -3.92. When it comes to negative numbers, a number is 'less' if it is further from zero. In this case, -3.92 is further from zero than -3.875.
So, -31/8 is greater than -3.92. In other words, -3.92 is 'less than' -31/8.

Note that the exact value of csc 60° with a rational denominator is (2√3)/3.
The reciprocal identity states that csc(theta) = 1/sin(θ).
Since we know that sin 60 degrees = √3/2, we can substitute this value into the reciprocal identity -
csc 60° = 1/(√3/2).
To rationalize the denominator, we multiply the numerator and denominator by the conjugate of the denominator -
csc 60°= (1/(√3/2)) * (√3/√3).
csc 60° = √3/(√3 * (√3/2)).
= √3/(√3 * √3/2).
= √3/(√9/2).
= √3/(3/2).
To divide by a fraction, we multiply by its reciprocal -
csc 60° = √3 * (2/3).
csc 60° = (2√3)/3.
So it is correct to state that , the exact value of csc 60° with a rational denominator is (2√3)/3.
