Suatu mesin dapat membuat suatu alat tahanan listrik dengan rata-rata tahanan sebesar 288,6 ohm dan simpangan baku 12,4 ohm. tahanan tersebut menyebar mengikuti distribusi normal. hitunglah probabilitas mesin tersebut mampu menghasilkan tahanan melebihi 300 ohm dan jika ada 3500 alat yang dihasilkan berapa banyak alat yang mempunyai tahanan antara 280 sampai denan 315 ohm ?

hi, i am not sure about this one but i think its d,

hope this !

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

7x7=4 so if u carry the 9 it will be 33
