1/24 was the case to select as per the specifications, when we add the condition of meeting 2 of the conditions at least, 1+2+3 (considering all the options and removing one condition) would be added to 1/24 - hence 7/24

Since each flavor,size and shape have same number of cookies, total possible cookies = 4*3*2 = 24
Nina wants : Lemon & Star & Large cookie
P(cookie her friend picks has at least 2 of 3 features)
At least 2 = Exactly 2 and Exactly 3 featured cookies
Exactly 3: Only 1 cookie will have all three features
Exactly 2: Only(Lemon & Star) = 1
Only(Large&Lemon) = 2
Only(Star&Large) = 3
Total favorable outcome = 1+1+2+3 = 7
Total outcome = 24
P(at least 2 feature) = 7/24
Option C

calculating the total possiblites
= flavoir * shape * size
= 4 * 3 * 2
= 24
now finall all posiblites wiht atlrast 2 feature matching.
case 1) all feature matching = 1
case 2)
shape no matching = 2 ways ( differnet shape)
case 3)
size not matchin = 1 way ( differnet size)
case 4
floavor not mathcing = 3 ways( differn flavor)
total = 7 ways
ansswer is 7/24
