Determine the probability There are five boys and four girls in a class. The teacher randomly selects one student to answer a question. Later, the teacher randomly selects a different student to answer another question. The first student is a boy and the second student is a girl.

20/81

Step-by-step explanation:

We need to multiply both probabilities to determine the probability of the events happening. There's a 5/9 chance for the first event and a 4/9 chance for the second one. Multiply them together and you get 20/81

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
