Answer:
111 / 190
Step-by-step explanation:
Total biscuits = 20
Plain, P = 12
Chocolate, C = 5
Currant, K = 3
Assume without replacement :
Probability that biscuit are of the same type :
P(plain) :
12 / 20 * 11 / 19 = 132 / 380
P(chocolate) :
5/ 20 * 4 / 19 = 20/ 380
P(currant) :
3/20 * 2 /19 = 6 / 380
Therefore,
Probability that biscuit is of the same type :
P(plain) + P(chocolate) + P(currant)
132/380 + 20/380 + 6/380
158 / 380 = 79 / 190
Therefore, probability that biscuit aren't of the same type :
1 - P(biscuit is of same type)
1 - 79/190
(190 - 79) / 190
111 / 190
Try 30 % i think that is correct

Answer:
The output for NAND gate is false if all the inputs are true. it is true if either A or B is False.
Step-by-step explanation:
Step1
NAND operator:
NAND is a logic or Boolean expression and is a combination of NOT and AND Gate.
NAND gate is built using various junction diodes and transistors.
Step2
The output of NAND can be 0 or 1. Here, LOW (0) and HIGH (1). 0 or 1 is commonly named as FALSE or TRUE respectively.
It is basically the complement of AND gate. If all its inputs are True or 1, then the output is False or 0 else if either A or B is 0 or 1 then it will give the output as TRUE.
Step3
Here, A and B are 2 inputs used to make the truth table for NAND.
In 1st row, when A and B are both 0, the output for NAND is 1.
Likewise, in 2st row and 3rd row, when either A or B is 0 or 1, the output for NAND is 1 that is TRUE.
But in last row, when both inputs A and B are true, then the output for NAND gate is FALSE or 0.
The diagram and truth table for NAND is shown below.
