The answer is 1/10.
There are in total 20 marbles in the bag:
3 green + 2 yellow + 6 blue + 9 red = 20 marbles
There are 2 yellow marbles of total 20 marbles. 2 of 20 can be expressed as:
2/20 = 1/10.
Therefore, <span>the probability of picking a yellow marble from the bag is 1/10.</span>
Answer:
1/4845
Step-by-step explanation:
The probability of selecting a defective cog first is
1/5
The second cog is
3/19
The third cog is
1/9
And the fourth cog is
1/17
Multiplying these together we get
1/5 * 3/19* 1/9 * 1/17 = 1/4845
