Answer:
1/5
In decimal = 0.2
Step-by-step explanation:
A box holds a white button, a brown button and a black button.
Hence:
Number of white button= 1
Number of brown button= 1
Number of black button= 1
Total number of buttons = 3
The probability of picking a white button then without replacing it, picking a brown button on the second pick is :
= P(White) × P(Brown) [ without replacement]
= 1/3 × 1/2
= 1/5
In decimal = 0.2
