That creates the number 82,190
The probability of event A and B to both occur is denoted as P(A ∩ B) = P(A) P(B|A). It is the probability that Event A occurs times the probability that Event B occurs, given that Event A has occurred.
So, to find the probability that you will be assigned a poem by Shakespeare and by Tennyson, let Event A = the event that a Shakespeare poem will be assigned to you; and let Event B = the event that the second poem that will be assigned to you will be by Tennyson.
At first, there are a total of 13 poems that would be randomly assigned in your class. There are 4 poems by Shakespeare, thus P(A) is 4/13.
After the first selection, there would be 13 poems left. Therefore, P(B|A) = 2/12
Based on the rule of multiplication,
P(A ∩ B) = P(A) P(B|A)P(A ∩ B) = 4/13 * 2/12
P(A ∩ B) = 8/156
P(A ∩ B) = 2/39
The probability that you will be assigned a poem by Shakespeare, then a poem by Tennyson is 2/39 or 5.13%.
Answer:
Step-by-step explanation:
<u>Negative four is at least six less than a number</u>
<u>Sum of a negative two & nine times a number is less than seventy nine</u>
- -2 + 9x < 79 ⇒ 9x < 81 ⇒ x < 9
<u>Combined inequality:</u>
1 i think? sry if im wrong
Answer:
AB = 12 cm
Step-by-step explanation:
AB/BC = XY/BY
From the above question:
AB = ??
BC = 9cm
XY = 4cm
BY = 3 cm
AB/9 = 4/3
Cross Multiply
AB × 3 = 9 × 4
AB = 9 × 4/3
AB = 12 cm
Therefore, Length AB = 12cm
