Answer:

Step-by-step explanation:
probability of selecting a girl from students is 
probability of girl wearing sneaker from girls is
or 
hence, probability of selecting a girl wearing a sneaker will be,
⇒ probability = probability of delecting a girl from students × probability of girl wearing sneakers from girls
⇒ probability = 
⇒ probability = 
The answer to this question would be: B. JK and LM meet at a right angle.
The reversed T symbol in this question means "perpendicular". That means the JK and LM line have 90-degree angle difference. A straight angle is 180 degree and right angle mean 90 degrees.
A perpendicular line should be in the same plane and intersect each other.
The area of square TUVW = 3×3 = 9 square units
1 square unit = 4 head lettuces
9 square units = 9×4 = 36 lettuces
Area of plot QRST = length × width = 12×6 = 72 square units
36 vegetables for every 9 square units
We have 72÷9 = 8 lots of 9 square units
Total vegetable = 8 × 36 = 288 vegetables
We can have 8 different vegetables, each type can have 36 vegetables
