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
It would depend if they are going to the same work or not.
2l + 2w = p
If you already have perimeter and length, you can use this formula to solve for width.
The answer is 2.35714285714!
hope this helps!!
