1/4 * 1/3 * 1/2 * 1/1 = 1/24 chance that all 4 letters are placed in the correct envelopes.
With the first envelope, there are 4 choices of letters, so the probability of picking the correct letter is 1/4.
With the second envelope, there are 3 remaining letters, so the probability of picking the correct letter is 1/3.
The same logic follows the the third and final letter.

Answer:
The rate of interest for compounded daily is 2.1 6
Step-by-step explanation:
Given as :
The principal investment = $ 98,000
The Time period for investment = 7 years
Let The rate of interest compounded daily = R %
The Amount at the end up = $ 114,000
<u>From compounded method</u>
Amount = Principal ×
Or, $ 114,000 = $ 98,000 ×
Or, =
or, 1.16326 =
or, = 1 +
1.00005919 - 1 =
or, 0.00005919 =
∴ R = 0.00005919 × 365000 = 2.16
Hence the rate of interest for compounded daily is 2.1 6 Answer
