P(all 4 are male) = 1/2^4 = 1/16 ( assuming probability of 1 male = 1/2)
P( 3 are male) = 1/2^4*4 = 1/4
The rest will have at least 2 females
So probability of at least 2 females) = 1 - 1/16 - 1/4 = 1 - 5/16 = 11/16 answer
<span>The factors of 12 are : 1, 2, 3, 4, 6, 12.
The factors of 15 are : 1, 3, 5, 15.
1 and 3 are the only common factors (numbers which are factors of both 12 and 15).</span>
<span>Therefore, the highest common factor of 12 and 15 is 3.</span>
