There are 8 possible outcomes when you throw a coin three times:
Out of these combination, the ones with exactly two heads are
So, 3 combinations out of 8 have exactly two heads. This means that the probability of having two heads with three coin throws is 3/8
Answer:
1/ 10 ; 1/15
Step-by-step explanation:
Given that:
Fraction with brown hair = 2 /5
1/4 of brown haired girls have long hairs
2/3 of long, brown haired girls have green eyes.
Fraction of girls with long, brown hair :
1/4 of 2/5
1/4 * 2/5 = (1*2) / (4*5) = 2/ 20 = 1/10
Fraction with long, brown hair and green eyes :
2/3 of Fraction with long, brown hair :
2/3 of 1/10
2/3 * 1/10 = (2*1) / (3*10) = 2/30 = 1/15
Answer: Angle 2
The 7.5 cm side is opposite angle 2, so opposite = 7.5
The 18 cm side is adjacent to angle 2, so adjacent = 18
Therefore, tan(angle 2) = opposite/adjacent = 7.5/18
Replace "angle 2" with "A" and we have tan(A) = 7.5/18
