Question

the probability of picking up the prime numbers when number cards of 10 to 40 are shuffled​

Answer 1

the total number of outcome is 30.

The total number of favourable outcome is 8.

P=8/30

=4/15

Answer 2

$\huge \bold{heya....}$

$\mathfrak{here \: is \: u \: r \: answer}$

$\bold{prime \: numbers} \: are \\ the \: numbers \: that \: can \: be \: \\ divided \: exactly \: only \: by \\ itself \: and \: 1$

▪️The Prime Numbers between 10 to 40 are
11, 13, 17, 19, 23, 29, 31, 37.

So... The Possible outcomes are 8

And Total number of outcomes = 30

▪️Probability of an event = Possible Outcomes by Total Number of Outcomes...

▪️8 /30 = 4/ 15 (divided by 2)

Hence.. The probability of picking card with a prime number is 4/15

Have a Great day ahead
