Which statement is true? the probability of randomly selecting a student who has a favorite genre of drama and is also female is
tankabanditka [31]

The correct statement is that the probability is B. Event F for female and event D for drama are independent events.

<h3>What are independent events?</h3>

It should be noted that two events are independent when the occurence of one doesn't affect the probability of another one occuring.

The probability of females will be:

= 3/5 = 0.6

The probability of drama will be:

= 40/240 = 0.167

In this case, they're both independent.

x + y = 30
6x + 9y = 240

3y = 60
y = 20

x = 10

20 BLTs for $2.50, 10 tuna for $1.50

which of the following best describes the technique used to graph the equation using the slope and y-intercept ? Y=5x+10
Vinvika [58]
The slope-intercept is y = mx+b. You can use this as a technique for graphing to make the experience easier. The "5" would be the slope or rise/run of the line. The 10 would be where it started on the y-intercept. You could also say it would be (0,10). Since the slope is positive than it would be going in an upward direction. That is why this technique is good for graphing. I hope this helps you and please put me as the brainliest answer. :)
