Answer:
1/26
Step-by-step explanation:
This is a case of joint probability. We find the two probabilities separately and then multiply the results together:
P(odd number on cube) = 3/6 = 1/2; P(7 from a deck)) = 13/52 = 1/13
Then the desired joint probability is (1/2)(1/13) = 1/26
Note that the two events here are entirely separate and independent.
Answer:
Step-by-step explanation:
f(x) = 250(10) + 10 = 2500 + 10 = 2510
Answer:
Probabilty of first component drawn defective= 0.1161
Probability of second component drawn defective= 0.1560
Step-by-step explanation:
Total component = 9
Defective component= 3
Non-defective component= 6
Probability of defective= 3/9
= 0.3333
Probabilty of non defective= 1-0.3333
= 0.6666
Probabilty of first component drawn is defective
= 9C1(0.333)¹(0.6666)^8
= 9(0.3333)(0.0387)
= 0.1161
Probabilty of second component is defective
= 8C1(0.3333)¹(0.6666)^7
= 8(0.3333)(0.0585)
= 0.1560
Answer:
-259
Step-by-step explanation:
<span>Student 2: -9 + (6 + 9) - 42
-9 + (9 + 6) - 42
(-9 + 9) + 6 - 42
0 + 6 - 42
0 + 6 - 16
0 + 6 + (-16)
6 + (-16)
-10</span>

hope this helps
since it is only addition and subtraction, you can mix the orders up, as long as you use the correct sign
