you pick a marble from this bag.
what is the probability you will choose either a black or a white marble?
remember to simplify
a) $\frac{4}{10}$
b) $\frac{3}{10}$
c) $\frac{3}{5}$
d) $\frac{6}{10}$

Explanation:

Step1: Count total marbles

Count all marbles in the bag: $3 + 4 + 3 = 10$

Step2: Count target marbles

Count black + white marbles: $3 + 3 = 6$

Step3: Write raw probability

Probability = $\frac{\text{Target marbles}}{\text{Total marbles}} = \frac{6}{10}$

Step4: Simplify the fraction

Divide numerator and denominator by 2: $\frac{6\div2}{10\div2} = \frac{3}{5}$

Answer:

c) 3/5
