Step-by-step explanation:
The successful events would be 34 , 40 41 42 43 44 45 46 47 48 49
The total number of ways 19 when you count from 31 to 49
P(1 four) = 11/19 = 0.5789

Answer:
n > -4/3
Step by step
Step by step solution :
Step 1 :
Equation at the end of step 1 :
25 - (0 - 3 • (4n - 3)) > 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
12n + 16 = 4 • (3n + 4)
Equation at the end of step 3 :
4 • (3n + 4) > 0
Step 4 :
4.1 Divide both sides by 4
4.2 Divide both sides by 3
n+(4/3) > 0
Solve Basic Inequality :
4.3 Subtract 4/3 from both sides
n > -4/3
Answer:
a) 0.50575,
b) 0.042
Step-by-step explanation:
Example 1.5. A person goes shopping 3 times. The probability of buying a good product for the first time is 0.7.
If the first time you can buy good products, the next time you can buy good products is 0.85; (I interpret this as, if you buy a good product, then the next time you buy a good product is 0.85).
And if the last time I bought a bad product, the next time I bought a good one is 0.6. Calculate the probability that:
a) All three times the person bought good goods.
P(Good on 1st shopping event AND Good on 2nd shopping event AND Good on 3rd shopping event) =
P(Good on 1st shopping event) *P(Good on 2nd shopping event | Good on 1st shopping event) * P(Good on 3rd shopping event | 1st and 2nd shopping events yield Good) =
(0.7)(0.85)(0.85) =
0.50575
b) Only the second time that person buys a bad product.
P(Good on 1st shopping event AND Bad on 2nd shopping event AND Good on 3rd shopping event) =
P(Good on 1st shopping event) *P(Bad on 2nd shopping event | Good on 1st shopping event) * P(Good on 3rd shopping event | 1st is Good and 2nd is Bad shopping events) =
(0.7)(1-0.85)(1-0.6) =
(0.7)(0.15)(0.4) =
0.042
